Description

Technical Field

[0001] The utility model relates to the technical field of fly ash classifiers, in particular to a fly ash classifier with centripetal and high efficiency. Background Art

[0002] With the increasing maturity and promotion of fly ash comprehensive utilization technology in my country, fly ash comprehensive utilization is no longer limited to environmental protection requirements. The huge economic benefits of fly ash comprehensive utilization have been reflected. The effect of fly ash on cement and concrete is closely related to its fineness. The smaller the fineness, the better the effect. The closed-circuit grinding system composed of mills and powder selectors can increase the output by 10-20% compared with the open-circuit grinding system without powder selectors. Therefore, the use of powder selectors as supporting equipment for mills in grinding operations is one of the main ways to increase production:

[0003] Application number: "CN202122585947.1" The utility model discloses a fly ash powder classifier with centripetal efficiency, including a powder classifier body, a centripetal structure is arranged inside the powder classifier body, and a dispersion structure is arranged inside the powder classifier body and above the centripetal structure; the centripetal structure comprises: a fixed ring, a bearing, a rotating stopper sleeve, a plurality of first stop bars, a first gear ring, a first motor and a first driving gear; the fixed ring is mounted on the inner wall surface of the powder classifier body, the bearing is mounted on the inner wall surface of the fixed ring, and the rotating stopper sleeve is movably inserted on the inner ring of the bearing. The utility model relates to the technical field of powder selection equipment, and is provided with a dispersion structure and a centripetal structure. The dispersion structure disperses the fly ash entering the powder classifier so that the fly ash rotates and falls, and the centripetal structure makes the dispersed fly ash have a centripetal tendency, while maintaining the tendency of the fly ash to rotate and fall, so as to avoid the dispersed fly ash from sticking to the inner wall of the powder classifier, thereby improving the centripetal efficiency and the powder selection efficiency;

[0004] The above patent is the conventional structure of the current conventional powder classifier. Before the current fly ash falls into the powder classifier, a large amount of fine powder will accumulate to form coarse powder. In the subsequent screening, multiple cycles of powder selection are required, which leads to a long operating time of the equipment and increases the production cost. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Figure 1-4 As shown, the utility model provides a centripetal and efficient fly ash classifier, comprising a machine body 1, a feeding pipe 11 is installed at one end of the upper surface of the machine body 1, a first rotating rod 12 and a second rotating rod 13 are respectively rotatably inserted on the feeding pipe 11, the first rotating rod 12 is located below the second rotating rod 13, a beating plate 121 is fixedly provided at one end of the first rotating rod 12 and the second rotating rod 13 located inside the feeding pipe 11, and a connecting rod 12 is provided at one end of the first rotating rod 12 and the second rotating rod 13 located outside the feeding pipe 11 A connecting component is provided, a base 2 is fixedly provided at the bottom of the feed pipe 11, and the base 2 is fixedly installed on the upper surface of the outer wall of the body 1. The feed pipe 11 and the base 2 are communicated with the interior of the body 1. Two symmetrically distributed baffles 21 are movably inserted in the base 2. The two baffles 21 can cover the bottom of the feed pipe 11. A horizontally arranged moving plate 23 is provided above the outer wall of the body 1 near the base 2. The moving plate 23 is connected to the adjacent baffles 21 through a long rod 22, and a driving component is provided between the moving plate 23 and the baffles 21.

[0020] The connecting assembly includes a connecting shaft 14, and the connecting shaft 14 is provided with two rotatable settings outside the feed pipe 11. The two connecting shafts 14 are connected by two meshing driving gears 15 in the middle. The two connecting shafts 14 are respectively connected to the first rotating rod 12 and the second rotating rod 13 through a belt 16 transmission. The two meshing driving gears 15 can make the rotation directions between the first rotating shaft 27 and the second rotating shaft 27 opposite, so that the material in the feed pipe 11 is chaotic, thereby making the beating of the fly ash entering the feed pipe 11 more effective; a motor 17 is installed outside the feed pipe 11 near the second rotating rod 13, and the output end of the motor 17 is coaxially fixed on the second rotating rod 13. The motor 17 can provide power for the overall operation of the device and is convenient for the staff to operate.

[0021] The driving assembly includes a movable groove 24, which is opened through the movable plate 23. A push block 25 is movably provided in the movable groove 24. A vertically arranged rotating shaft 27 is provided at the middle end above the movable plate 23. A swing plate 26 is fixedly provided at the bottom of the rotating shaft 27. The end of the swing plate 26 is fixedly provided above the push block 25. The movable plate 23 can be pushed to move repeatedly by the swing plate 26 and the push block 25, thereby driving the baffle 21 to open intermittently, thereby increasing the residence time of fly ash, increasing the contact time of the flapping plate 121 with the fly ash, and improving the effect of breaking up the fly ash.

[0022] A horizontally arranged support plate 3 is fixedly provided on the side wall of the base 2, and the rotating shaft 27 rotates and penetrates the support plate 3. The support plate 3 can support the rotating shaft 27, thereby ensuring that the rotating shaft 27 can rotate stably; a vertically arranged transmission shaft 31 is provided on the support plate 3 near the rotating shaft 27, and a small gear 33 is fixed on the transmission shaft 31. A large gear 32 meshing with the small gear 33 is fixed on the rotating shaft 27. The top of the transmission shaft 31 is connected to one end of the second rotating rod 13 through two meshing bevel gears 34. The large gear 32 and the small gear 33 are arranged to adjust the movement speed of the flapping plate 121 and the baffle 21. The driving of the small gear 33 can make the flapping plate 121 rotate faster, thereby better discharging the fly ash. When the large gear 32 is driven, the baffle 21 can move slower, and the opening time of the bottom of the feed pipe 11 is increased, thereby increasing the residence time of the fly ash, and better increasing the contact time of the flapping plate 121 with the fly ash.

[0023] A support rod 5 is fixedly provided on the side wall of the base 2, and sliders 51 are fixedly provided at both ends of the movable plate 23. The sliders 51 can movably penetrate the support rod 5. The support rod 5 and the slider 51 can support the movable plate 23, so that the movable plate 23 can move stably; the beating plates 121 are arranged in a ring-shaped distribution on the first rotating rod 12 and the second rotating rod 13. The beating plates 121 distributed in a ring-shaped distribution can contact the fly ash more fully, thereby improving the effect of beating the fly ash.

[0024] Working principle: In actual use, fly ash enters the machine body 1 through the feed pipe 11 for powder selection operation. Before this, the motor 17 can drive the second rotating rod 13 to rotate, and the second rotating rod 13 can drive the first rotating rod 12 to rotate through the belt 16 and the driving gear 15. At this time, the beating plates 121 on the first rotating rod 12 and the second rotating rod 13 can rotate at the same time to beat the fly ash and break it up. Since the first rotating rod 12 and the second rotating rod 13 are connected by two meshing driving gears 15, the first rotating rod 12 and the second rotating rod 13 will rotate in opposite directions at the same time, making the material in the feed pipe 11 chaotic, so that the breakup effect on the fly ash entering the feed pipe 11 is more effective;

[0025] When the second rotating rod 13 rotates, the transmission shaft 31 can be driven to rotate through two meshing bevel gears 34, and the transmission shaft 31 can drive the rotating shaft 27 to rotate. At this time, the rotating shaft 27 drives the swing plate 26 and the push block 25 to rotate. At this time, the push block 25 will drive the movable plate 23 to move. At this time, the movable plate 23 will pull the baffle 21 to move through the long rod 22. As the swing plate 26 continues to rotate, the push block 25 will continue to move from one end of the movable groove 24 to the other end. At the same time, the movable plate 23 will be driven by the push block 25 to continuously move back and forth on the side wall of the base 2. At this time, the movable plate 23 will drive the baffle 21 to move repeatedly. The simultaneous operation of the two baffles 21 can make the bottom of the feed pipe 11 open intermittently, thereby increasing the residence time of the fly ash, increasing the contact time of the slapping plate 121 with the fly ash, and improving the effect of breaking up the fly ash. The accumulated coarse powder is broken up when it enters the machine body 1, so that the machine body 1 can better select the powder, thereby reducing the operating time of the equipment and reducing the cost.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
